Define a new way that attribute definitions can be introduced such that the parser can invoke the third-party custom logic they provide; and additionally permit them to be attached to more types of target than Perl currently allows.
Still currently in draft as I work out a few more minor questions, but now at the stage where it should be suitable for comments.
Many small updates clarifying wording, narrowing down a few open issues, adding more specification in terms of new API support functions and behaviours.
Abstract
